What is heat conduction?

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research. For example, knowing how ...

The coolest LEGO in the universe

For the first time, LEGO has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy.

The first topological acoustic transistor

Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials ...

Storing a Lightning Bolt in Glass for Portable Power

(PhysOrg.com) -- Materials researchers at Penn State University have reported the highest known breakdown strength for a bulk glass ever measured. Breakdown strength, along with dielectric constant, determines how much energy ...

Magnetism drives metals to insulators in new experiment

Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal ...
